Quinton Carter to have season-ending knee surgery

The Broncos have lost second-year safety Quinton Carter for the season.

A 12-game starter as a rookie, Carter was placed on injured reserve Saturday because of an aggravated knee surgery. Carter will undergo microfracture surgery on the knee next week.

With Carter now off the roster and middle linebacker Joe Mays suspended for the game Sunday against Oakland, the Broncos replaced them on their 53-man roster with rookie safety Duke Ihenacho and second-year middle linebacker Mike Mohamed. Ihenacho and Mohamed were promoted from the Broncos’ practice squad.

Veteran Keith Brooking is expected to start at middle linebacker Sunday with Wesley Woodyard again starting at weakside linebacker.
